A new concept for cleanup of contaminated properties and hazardous waste sites applicable under federal and state regulatory programs is helping clients achieve both business and regulatory goals at their sites. The concept, called 'Integrated Site Closure', is the seamless integration and delivery of services necessary to reach regulatory closure of contaminated properties. Regulatory closure ...

The Kentucky Research Consortium for Energy and the Environment (KRCEE) worked with the U.S. Department of Energy (DOE) last summer to introduce new approaches and technologies to the site cleanup program operating at the Paducah Gaseous Diffusion Plant (PGDP) in western Kentucky. A Triad demonstration was conducted at PGDP's Area of Concern (AOC) 492 that integrated several real-time ...

The U.S. Naval Facilities Engineering Command Southwest (NAVFAC SW) used the Triad approach to collect an integrated hydrogeologic and chemical dataset for expediting and optimizing characterization of a volatile organic compound (VOC) plume at Naval Base San Diego (NBSD), CA. The 295-acre 'IR Site 22' was identified in 2003 when VOC concentrations reaching 100 mg/L were reported in an upgradient ...

Abstract Rapid, accurate on site determination of arsenic and heavy metal levels in soil is a powerful tool in efforts to rebuild and revitalize abandoned and under-utilized industrial properties. The EPA is actively spearheading initiatives to encourage assessment, clean-up and re-use of these industrial properties. In the case of heavy metals (often the eight RCRA metals Pb, As, Cd, ...

For example, published reports on the use of the “Principles” at DOE sites show savings of millions of dollars and avoidance of months or years of effort at sites in Nevada, Ohio, Kentucky, and South Carolina. At a site in South Carolina, ongoing challenges with implementing a cleanup program led to the regulators calling a “time out” in enforcing compliance agreement milestones and a rethinking ...

A presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site. EPA is establishing presumptive remedies to accelerate site-specific analysis of remedies by focusing the feasibility study efforts. EPA expects that a presumptive remedy, when available, will be used for all CERCLA sites except under ...

Polyethylene diffusion bag (PDB) samplers are low-density polyethylene bags containing deionized water, used to collect water samples in groundwater wells for laboratory analyses of volatile organic compounds (VOCs). PDB samplers are passive devices, relying on the movement of groundwater from the aquifer or water-bearing zone through the screen or open interval of a well. VOCs in groundwater ...

Introduction Green building has received increased attention over the past decade from both environmental economists and policymakers. While there is no single definition of “green buildings” or its related policy, researchers and organizations tend to emphasize resource efficiency in building and reducing the impacts of buildings on human health and the environment. ...

The summer of 2015 was surprisingly busy in the industrial biotechnology policy and regulatory arenas with three important announcements generating lots of buzz. On July 2, 2015, theWhite House Office of Science and Technology Policy (OSTP), the Office of Management and Budget (OMB), the US Trade Representative, and the Council on Environmental Quality issued a memorandum directing the US ...
